Can Police Authorize Informants to Sleep with Targets of an Investigation

My question involves civil rights in the State of: Ohio

I have heard that it is unlawful (or at least contrary to established police procedure) for the police to authorize an informant to engage in sexual intercourse with the target of a police investigation. Could someone cite a specific law or police policy that is violated when the police authorize an informant to sleep with a target of an investigation? What crimes could the police and the informant be charged with if they engage in sexual relations with a target? Again, please provide reference to a specific law or policy...

Another citation of North Dakota Law:

http://www.legis.nd.gov/cencode/t29c29-5.pdf (29-29.5-05. Written agreement required ---- "A warning that sexual relations with an intended target of a police investigation is a
violation of the agreement and may be a violation of the law")

Another citation:

"Having sex with the suspects in the cases constitutes entrapment and violates the defendants’ due process rights, according to Florida case law cited by defense lawyers. Also, any sexual relationship between an informant and a target violates the rules of nearly every law enforcement agency, federal, state or local."

So what is the crime?
